Almost any gun can be fitted with Briley choke tubes, either lead shot only or steel compatible. Only the steel in the more expensive steel shot Briley choke tubes is different from the lead shot tubes. Threads in the tubes and cut into the barrel wall are the same.
Wall thickness is rarely a problem. Superposeds are said to be a possible exception due to the way the muzzles come together. I have had one 12 ga Super fitted with Brileys that worked out OK, but maybe I was just lucky.
The purchase of a few of the more expensive steel shot tubes should make a gun originally set-up with Brileys for lead usable with steel shot. I personally would stick with relatively open steel shot tubes in any case.
